Google has made a small update to Google Translate, making it easier to switch between translations to and from different languages. There are now tabs for both sides of the translation pair, pre-filled with the languages used the most.
There are three tabs for each side and the language selection on each seems to be based on the ones users selected the most previously.
Changing the languages selected is a bit confusing, selecting a new one will replace the oldest option in the tabs.
This may be a bit confusing at first since you'd expect it to replace the language you currently have selected in the tabs.
Google Translate now also highlights the last three languages you used, to make them easier to spot in the drop down list, which is rather cluttered since Translate now supports so many languages.
